On-Site Medical Center at Maris Grove

Individualized Senior Health Care

You don’t have to travel very far for excellent Delaware County senior health care. Maris Grove proudly offers Erickson Health Medical Group, a full-service medical practice on-site, devoted to seniors. Our medical center is conveniently located on the Maris Grove campus and easily accessible for all residents. It’s staffed by professional physicians who get to know you as an individual instead of a patient—making your health a top priority.

Quality time and attention.You’ll develop a personal relationship with your physician, since they have time to get to know about you, your health goals, and your concerns.

Same-day appointments.Because our doctors see exclusively Maris Grove residents, they can usually see you on the same day you call when you become a patient of our practice.

Superior convenience. The medical center is just an indoor walk away from your apartment home. And you can still take advantage of its benefits, even if you prefer to keep your current doctor.

It’s handy to have the medical service right here just in case I need closer attention.
